Engine compartments are becoming ever tighter and more compact. For this reason, due to space limitations automobile manufacturers are increasingly relying on hose clamps with close-fitting clamp tabs, which with conventional tools are loosened only with difficulty or are almost impossible to loosen in very tight spaces. With the SZ-3000 any hose clamp can be opened quickly and without great effort. The delivery kit includes two flexible Bowden cables each with different clamping jaws. The clamping jaws are placed on the hose clamp tabs and the hose clamp can immediately be opened in a continuous motion(!) and without great effort. The Bowden cables can be changed easily and conveniently.
